The title complex trans-[Cu(sac)2(en)2] (sac = saccharinato, en = ethylenediamine) has been obtained accidentally by the reaction of piperazine (ppz) with [Cu(sac)2(H2O)4]·2H2O in butanol solution. During the reaction, ppz was presumably decomposed to produce en which then coordinated to copper(II) to yield the title complex. trans-[Cu(sac)2(en)2] has been characterized by elemental analysis, IR, UV-VIS, magnetic measurements and single crystal X-ray diffraction. The compound crystallizes in space group [image omitted] (No. 2) and it consists of neutral units linked by bi- and trifurcated N-H···O hydrogen bonds into chains which are further connected by aromatic π-π stacking interactions forming a three-dimensional supramolecular network. The copper(II) ion in [Cu(sac)2(en)2] sits on a inversion centre and is octahedrally coordinated by two neutral en and two anionic sac ligands. An elongated distorted octahedral geometry along the Cu-Nsac bonds is a consequence of the Jahn-Teller effect. The en ligand acts as a bidentate (N,N') chelating ligand, while sac is N-coordinated. IR and UV spectra and thermal analysis are in agreement with the crystal structure. |
